Clinical Significance of Detecting Fetal Pulmonary Vein Blood Flow Parameters and Left Ventricle Tei Index by Color Ultrasound in Gravidas with Hypertensive Disorders of Pregnancy
摘要
Abstract
Objective:To explore the clinical significance of detecting fetal pulmonary vein blood flow parameters and left ventricle Tei index by color ultrasound in gravida with hypertensive disorders of pregnancy(HDP).Method:A total of 80 gravidas with HDP admitted to the First People's Hospital of Jingdezhen from March 2022 to January 2024 were prospectively selected and included in the HDP group(20 cases of gestational hypertension,31 cases of non-severe preeclampsia,29 cases of severe preeclampsia),and 80 gravidas with normal prenatal examination were selected and included in the control group during the same period.Fetal pulmonary vein blood flow parameters[peak systolic flow rate(S),peak diastolic flow rate(D),left atrial reverse systolic flow rate(A),peak velocity index vein(PVIV),pulsation index(PI)]and left ventricular Tei index were detected by color ultrasound in all included subjects.The fetal pulmonary vein blood flow parameters and left ventricle Tei index were compared between HDP group and control group,and in gravidas with different disease severity.The incidence of fetal distress was observed during follow-up,and the predictive value of the above ultrasound indexes in fetal distress were evaluated by receiver operating characteristics(ROC)curve.Result:The fetal left ventricular Tei index,PI and PVIV in HDP group were higher than those in control group,and S,D and A were smaller than those in control group,the differences were statistically significant(P<0.05).The left ventricular Tei index,PI and PVIV in gravidas with severe preeclampsia were higher than those in gravidas with non-severe preeclampsia,and those in gravidas with non-severe preeclampsia were higher than those in gravidas with gestational hypertension,the differences were statistically significant(P<0.05).The fetus S,D and A of gravidas with severe preeclampsia were smaller than those of gravidas with non-severe preeclampsia,and those of gravidas with non-severe preeclampsia were smaller than those of gravidas with gestational hypertension,the differences were statistically significant(P<0.05).Among gravidas with HDP,18 cases had fetal distress and were included in the occurrence group,62 cases did not have fetal distress and were included in the non-occurrence group.The fetal left ventricular Tei index,PI and PVIV in the occurrence group were higher than those in the non-occurrence group,and the S,D and A were smaller than those in the non-occurrence group,the differences were statistically significant(P<0.05).The area under ROC curve of left ventricular Tei index combined with pulmonary venous flow parameters predicted fetal distress in gravida with HDP was 0.889,which was higher than that detected by each indicator alone(P<0.05).Conclusion:Left ventricular Tei index and pulmonary vein flow parameters can be used to evaluate fetal cardiac function in gravidas with HDP,and have a certain value in predicting the occurrence of fetal distress.关键词
